HIDE-FLESHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 467,216, dated January19, 1892.

Application filedMarch I7, 1891- Serial No. 385,371. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR E. WHITNEY, of Winchester, in the county ofMiddlesex and State of Massachusetts, have invented. certain new anduseful Improvements in Hide- Fleshing Machines, of which the following,taken in connection with the accompanying drawings, is a specification.

My invention relates to hide-fieshing machines; and it consists incertain novel features of construction, arrangement, and combination ofparts, which will be readily understood by reference to the descriptionof the drawings and to the claims hereinafter given, in which myinvention is clearly pointed out.

Figure l of the drawings is an end elevation of a machine embodying myinvention, with a portion of the toggle cut in section. Fig. 2 is avertical transverse section on line a: w on Fig. 3 with the treadlerodguiding bearing cut in section on a different plane. Fig. 3 is a frontelevation of the left half of the machine, with the table and the looseand reversing pulleys shown in section. Fig. 4 is a transverse sectionof the spirally-bladed hide-spreadin g cylinder drawn to an enlargedscale, and Fig. 5 is a similar view of the spirally-bladedfleshing-cylinder.

In the drawings,A and A are the. end

frames of the machine, which are connected together by the tie-girts B Bin a well-known manner.

O is the bed and lower feed-roll, mounted in bearings'in boxes fitted toand movable obliquely in the slot 0 of the frames A and A. D is theupper feed-roll, mounted in like manner in boxes a, which are movable inthe slots D of said frames. The rolls 0 and D are geared together, so asto revolve in unison, by the gear-wheels E and E, (shown only in dottedlines in Fig. 2,) said gear-wheels being provided with extra-long teeth,so that said rolls may be separated, as shown in the drawings, withoutbeing thrown out of gear.

F is a cylinder provided with knife-edged blades 0 arranged spirallythereon in opposite directions from the center of its length,substantially like the hide-working knifecylinder described in theLetters Patent No. 341,976, granted to me May 18, 1886. The

knife-cylinder F is mounted in fixed bearings secured to the frames Aand A at the upper ends of the slots 0, as indicated by dotted lines inFig. 1, the blades of said cylinder serving to cut away. and remove thesuperfluous flesh from the hide or skin.

G is a cylinder mounted in movable boxes 19, fitted to the slot G, andprovided with a plurality of blades d, having their outer edges rounded,as shown in Fig. 4, and arranged spirally in opposite directions fromthe center of its length, so as to serve to spread the hide or skinlaterally and remove all wrinkles therefrom.

The fleshing-cylinder F is revolved at a high rate of speed by means ofthe pulley F, secured upon one end" of its shaft, as shown in Figs. 1and 3, and a suitable belt leading therefrom to a main or counter shaft,(not shown,) and the spreading-cylinder is driven in a similar mannerthrough the medium of a pulley similar to F, secured upon its shaft atthe opposite side of the machine, and not shown in the drawings.

The shaft of the cylinder G has secured thereon at the left of the frameA the pulley H, from which the belt I leads to and around one or theother of three pulleys J, J, and J arranged side by side on the, sleeveK, mounted and revoluble on the stud K, set in the frame A. The pulley Jis firmly secured to the sleeve K, so as to revolve therewith, while thepulleys J and J are fitted to revolve freely upon said shaft betweensaid pulley J and the pinion e, which is formed in one piece with thesleeve K, so as to revolve therewith. The teeth of the pinion e engagewith the teeth of the spur gear-wheel L, upon the hub of which issecured the pinion f, the teeth of which engage the teeth of the spurgear-wheel M, which is mounted upon a stud set in the frame A andengages with and imparts motion to the gear-wheel N, secured upon theshaft of the lower feed or bed roll 0, as shown. The hub of the pulley Jhas secured thereon the pinion g, the teeth of which are in engagementwith the teeth of the pinion g, loosely mounted upon a stud set in theframe A and having secured thereto another pinion g which engages withthe teeth of the gear-wheel L, so as to be revolved thereby when thebelt I is on the pulleyJ, as shown, or to impart motion to said gear Lin a direction the reverse of that indicated by the arrow thereon whenthe belt I is shipped upon the pulley J The boxes in which the roll 0has its bearings have formed in their under surfaces recesses or socketsto receive the upper end of the adjustable pintle h, set in thetoggle-link O, which is pivoted at 2' to the toggle-link O and thetreadle-rod P, as shown in Figs. 1 and 2. The toggle-link O is made upof the socketed upper section 7a, the rod provided with the collar orshoulder k and a male screw-thread at or near its lower end, the nut oradjustable collar 70 [it ted to said thread, the washer or disk R andthe spring 70 and the lower ends of said toggle-links O are stepped insockets in the frames A and A, as shown in Figs. 1 and 2.

R and R are two treadle-levers pivoted at l and Z to the frames A and A,respectively, and connected together at their front ends by thetreadle-board R and each of said levers has pivoted thereto at the rearof its fulcrum the lower end of one of the treadlerods P and at its rearend has pivoted thereto the lower end of arod m, which has formedthereon or secured thereto the long collar m, fitted to and movablevertically in a bearing in the stand S, said rod 122 extending upwardand through a bearing in the stand S and has fitted loosely thereon thecollar n and the spring '27,, as shown in Figs. 1, 2, and 3. Thetreadle-lever R also has pivoted thereto at 0 the lower end of the rodT, the upper end of which is pivoted to one arm of the elbow-lever U,the other arm of which is connected by the link 1) to the shipper-rod V,which is fitted to and movable endwisein a bearing q, secured to theframe A, and has secured to its outer end the shipper loop or fork V,all as shown in Figs. 1 and 3.

The upper feed-roll D and the spreading knife-cylinder G are pressedtoward the bedroll 0 by the springs r and 0", respectively, and themovements of said roll and cylinder are limited by the stop-rods s andsand nuts s and .9 all so constructed that said roll and cylinder mayyield against the tension of their springs to accommodate themselves tothe varying thickness of the hide or skin being acted upon.

\V is a fixed feed-table arranged nearly upon a level with the uppersurface of the bed-roll G when in its lowest position, and t is asupplementary table-leaf, made, preferably, of sheet metal and pivotedat a to the table V, and resting at its inner edge upon the uppersurface of the roll G, and adapted to be moved about its pivotalconnection to the table as the roll 0 is moved upward. T he bed-roll Cis provided with a covering of rubber or other suitable elastic materialin any well-known manner.

The operation of my invention is as follows The several parts of themachine being in the positions shown in the drawings, a hide or skin tobe fleshed is placed upon the table W, with its inner end resting uponthe upper surface of the roll C, with the flesh side up,when the machineis set in motion with the belt I upon the pulley J, when the severalrolls and cylinders will be revolved in the directions indicated by thearrows on Fig. 2, and the skin will be drawn inward and downward by therotation of the roll 0 until about one-half of the skin hangs downbetween the bed-roll and the spreading-cylinder G, when the operatorplaces his foot upon the treadle-board R and depresses it until thetoggles O O are straightened, the result of which is that the bed-roll,with the skin thereon, is moved upward into contact with the upperfeed-roll D,

the fleshing-cylinder F, and the spreadingcylinder G, and at thesametime the belt I is shipped upon the pulley J and the motions of thefeed-roll D and bed-roll C are reversed, so as to feed the skin backupon the table,

while at the same time the spiral blades on the cylinder G are spreadingthe skin laterally and the blades of the cylinder F are removing thesuperfluous flesh from the skin. W'hen the skin is withdrawn frombeneath the fleshing-cylinder, the operator removes his foot from thetreadle-board and the bed-roll drops to its normal position again, theset of the toggle being broken by the tension of the springs n n, whichwere compressed during the last part of the upward movements of the reararms of the treadle-levers R and R by the shoulder or collar on comingin contact with and raising the collar n and thus compressing saidspring. The skin is then turned end for end and the operation isrepeated.

By the use of my invention a perfect spreading of the skin is obtained,the wrinkles are completely removed, and the fleshing is accomplishedwithout danger of injury to the skin and at a comparatively small cost.

The construction of the toggle-link O is in two main parts, with thespring 70 tending to force said parts asunder, said spring being ofsufficient stiffness to hold the weight of the roll 0 and its boxes, butadapted to yield if an extra pressure or load is applied to said roll,as sometimes happens when the skin becomes doubled or folded betweensaid roll and the feed-roll D.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-
